How Do Solid Fats Affect You?

Your body relies on a proper intake of fats, carbohydrates and proteins to properly function. While you should consume fats from healthy sources, such as fish and vegetables, other fats, known as solid fats, can be harmful to your health. Avoiding solid fats in your diet can help you to avoid harmful health conditions including high cholesterol and heart disease. By making dietary changes, you can reduce the likelihood that blockages will form in your coronary arteries.

Solid fats are those that are solid at room temperature and include butter, milk fat, cream, lard, shortening, coconut oil, hydrogenated oil and palm and palm kernel oils, according to ChooseMyPlate.gov. These solid fats can come from natural sources, such as animal fats, and processed foods through a manufacturing process called hydrogenation. While solid fats may at time appear liquid, such as milk fats, the fats are suspended in oils or other liquids.

Known as low-density lipoprotein or LDL cholesterol, this cholesterol type is associated with an increased risk for heart disease. Solid fat consumption is associated with elevated LDL cholesterol levels, more so than saturated fats, according to The Harvard Medical School Family Health Guide. The more LDL fat you have in your blood, the more likely you are to develop blockages in your coronary arteries. If left untreated, blockages can lead to a heart disease and therefore, a heart attack. For this reason, The Harvard Medical School recommends avoiding solid fats.

Another type of cholesterol exists -- high-density lipoprotein or HDL cholesterol. Unlike LDL cholesterol, HDL cholesterol is considered the “good” form of cholesterol because it circulates through your blood, helping to remove LDL cholesterol. The higher the amount of HDL cholesterol in your blood, the less likely you are to experience adverse effects from excess cholesterol. Solid fats called trans fats or partially hydrogenated oils, are more likely to lower HDL cholesterol in your blood. Examples of foods that contain trans fats include packaged baked goods, such as cookies, cakes and breads.

Solid fats and added sugars compose an estimated 35 percent of an American’s total calorie consumption, according to MayoClinic.com. Foods high in solid fats are considered “energy dense,” which means they are high in calories. Excess calorie consumption is associated with an increased risk for weight gain because your body cannot burn off the high-calorie solid foods you have consumed. Instead of high-fat solid foods, MayoClinic.com recommends consuming low-calorie foods, such as vegetables, fruits, whole grains and low-fat dairy products.

How Does Increased Fiber Affect a Bowel Movement?

After your stomach breaks down food, the food moves through your digestive system, traveling into your small and large intestines. Your body absorbs what it needs and eliminates what it doesn't need via your stool. To move along your intestinal pathway, your digested food needs bulk, which is where fiber comes in. Gradually increasing your fiber intake may help to stimulate your bowels. Always speak with your physician about increasing your fiber intake to ensure it will not interfere with any medications you are taking.

Dietary fiber falls into two categories: soluble and insoluble. Soluble fiber is found in apples, citrus fruits, carrots and beans, and dissolves to create a gel-like paste. This fiber helps to slow the digestive process and keep your blood sugar at a steady level. Insoluble fiber affects your bowel movements because it remains unchanged in your body, adding bulk to your stool. Examples of insoluble fiber foods include whole-wheat flour, nuts and many vegetables, such as cauliflower and turnips.

Your digestive system moves digested material through your body via a system known as peristalsis, which is a wave-like motion. While your digestive system naturally engages in peristalsis, the more bulk your stool has, the better and faster it will move through your system. The walls of your intestines can push against the stool and send it on its way, helping you maintain digestive regularity. If you aren’t getting enough fiber in your diet or often experience constipation, increasing fiber could help stimulate peristalsis.

If you experience diet-related constipation, you can take two steps to improve the frequency of bowel movements -- increase your fiber and water intake. The increased insoluble fiber absorbs water as it travels along your digestive pathway, helping you to maintain regularity. The amount of fiber you need in your daily diet varies based on your overall health. As a general rule, men aged 50 and younger should have 38 grams of fiber per day, while women should eat 25 grams. Men aged 51 and older should eat 30 grams per day, while women should eat 21. Examples of a fiber-filled day could include starting with a whole-grain cereal, eating a serving of fruit with every meal and incorporating beans with lunch and dinner. While you’re increasing fiber, don’t forget to drink plenty of water. The right amount varies based on your activity level, overall health and climate, according to MayoClinic.com. As a general rule, if you rarely feel thirsty, your urine is clear to pale yellow and are drinking about eight 8-ounce glasses of water a day, you are likely drinking enough.

Increasing your fiber intake can speed up the rate at which your stool passes through your digestive tract, but you must use caution when increasing your fiber. Adding too much too soon can overload your digestive tract, causing fiber to pass through too quickly and resulting in gas, bloating and cramping. Increase your fiber intake gradually, adding a new serving every week until you reach your recommended intake.
